Why cant you use the same lancet twice to prick the finger?

The second time around, the lancet is not sterile and, therefore, risk of infection becomes a concern.


How do scientists report results?

By publishing them. Sometimes in a report, sometimes (or simultaneously) in an article, preferably in one of the major scientific journals like Nature or The Lancet.


Why cant you use the same lancet twice?

The needle is extremely small and thin and when it punctures the skin it gets damaged. This damage can make it painful to use more than once. EVEN MORE IMPORTANT is the fact that when the needle goes into the tissue it contacts blood which is sticky. The needle may look clean but it is now covered in microscopic bacteria and maybe even viruses. You can wipe it off but remember the needle is damaged and now storing bacteria in its microscopic cracks. Using it again now puts you at risk of bacterial infection. Remember you are sticking this into your blood supply so you are giving the bacteria a free ride to your capillaries and tissues. Bacterial infections can rapidly turn into dangerous situations especially in people not in optimal health (people with diabetes). Medicare/Medicaid and most insurances will cover enough lancets so you never have to use them twice. If you cant afford them you need to ask your pharmacist or health care professional for ways to get your lancets for discounted prices/free.

How do you carry out the test for glucose?

You can carry out a blood glucose test at home by using a blood glucose monitor. The test involves pricking your finger with a lancet, drawing a blood drop, and a test strip sipping up the blood for the monitor. A reading is given telling you the blood glucose level.
